Graphene just keeps getting weirder. Engineers at ETH Zurich have now managed to tweak the overachieving material so that some parts of a flake can be an electrical insulator while other areas act as a superconductor, just nanometers apart.

Eyeing solutions to our e-waste problem, engineers have developed the world's first fully recyclable printed electronics, demonstrated in a transistor that can be reduced to its original building blocks with the help of baths and sound waves.

Engineers at Stanford have created a new optical device that can easily manipulate light into basically any color desired. The system uses a series of modulators to fine-tune the frequencies of individual photons to change their color.

While most smartphones now have haptic feedback built into their screens, the whole screen buzzes, limiting the applications of the technology. A new touchscreen film, however, utilizes LEDs to only vibrate in specific areas.

While there are now many appliances that can be controlled via the internet, each one of those has to incorporate Internet of Things (IoT) electronics. Engineers have now created a system that moves those electronics to the home's wall outlets.

One display just isn’t enough for most people. If you’d rather not clutter up your desk with a whole bunch of screens, Lenovo has unveiled ThinkReality A3, a pair of augmented reality glasses that can project up to five virtual displays around you.

With colossal price tags to go with the colossal screen sizes, commercial applications have remained the main target for Sony's modular Crystal LED display technology. That continues with Sony's release of two new Crystal LED models.

In the world of fast-paced online gaming, every second of response time counts … in fact, make that every millisecond. The Impulse Neuro-Controller was designed with that in mind, as it detects mouse-clicks before they actually happen.

We've already heard about conductive inks that allow electrical circuits to be hand-drawn onto materials, using a ballpoint pen. Scientists have now developed a new such ink, which they claim is cheaper and more functional than others.

Diamond is a famously hard material, but now scientists have managed to stretch it further than ever before. Why? Stretching nanoscale samples changes their electronic and optical properties, which could open up a new world of diamond devices.

Folks entering shopping malls, airport lounges and office buildings could soon be welcomed by colorful greetings, important messages and of course adverts as they approach the sliding doors, thanks to a partnership between LG and Assa Abloy.

Some advanced electronic devices only function at extremely cold temperatures. Now engineers at NIST have developed a tiny cryogenic thermometer that uses a new mechanism to keep an eye on these sensitive instruments without taking up much room.
